Ok I'll throw my two cents into this heavily CRJ'd argument. First, I think it is hard for anyone who flies one aircraft to objectively say anything about the other. Evidently there are more CRJ boys on this site than ERJ.
I obviously fly the E145 and like it. Have ridden and jumpseated on the CRJ many times (ASA). Personally they both have good points and bad points, but lets face it, neither are Boeing

and thats all that really matters.
Things I dont like or have heard others dont like about the CRJ:
More expensive
higher operating costs
Had its own issues at first, and might still, but was simply a stretch Challenger
No FADEC or any other thrust management system
What is up with that Cessna 172 nose down landing attitude?!?!
LOUD EXPLOSION landing gear extension
Windows are nice if you are a child (very strangly arranged in the cabin - i.e. LOW)
that bathroom....god help ya if you are a chick or need to sh*t
Dunno about the crew bag storage - cant comment
Cockpit may be wider - but that center console sure does take it all away
Jumpseat is HELLA uncomfortable and my knees are up in the glare shield it seemed....im NOT tall and my legs were in the way of both guys trying to move their chairs backwards.
Like the Cabin height and width
Engines are wholly underpowered for that plane - in a word - pitiful.
ERJ:
Was quite unreliable early on - many MANY things have been fixed, and better engines put on them - VERY reliable aircraft now, especially at COEX and we can thank our excellent MX for that.
Was designed with what it does in mind, i.e. was built as an airliner, and wasn't just built from some business jet model
FADECS are very nice...closest thing you can get to auto throttles without them being auto throttles.
APU and the PACKS blow snow into the plane in the middle of August in Houston...you can't ask for better than that
IF you fly the airplane the way the company wants you too, well, then you have similar performance as the CRJ

...BUT if you Takeoff in Takeoff Power instead of ALT-TO, you have excellent thrust early on, climb in MAX CON Thrust instead of Climb Thrust and you can ALMOST pretend you are in a Boeing...about 300-310 in the climb and 1500'/min, otherwise its 280 in the climb and a thousand/min
I like the single window/isle seat - Row A, which all of our passengers fight over
the bathroom - well plenty of room for the mile high kind of experiences if you get my drift....AND you can spread out when you sh*t
narrow long cabin vs the short wider cabin - whatever
ERJ flys like most larger jets due to its length and therefore has the "normal jet" nose high landing attitude and profile
Loud Cockpit, just as in the CRJ...has to do with the lack of insulation according to the reps at Embraer and not the windows or the wipers. I have ridden in both aircraft and can't really see a difference in noise....both aircraft's pilots tend to wear the "clamp" style David Clark headsets.
and finally...my favorite...JETWAYS JETWAYS JETWAYS. At COEX there are no airstairs installed on the plane and now that EWR is finished, 95% of all our gates systemwide have the aircraft at a jetway. Its tall enough to easily fit a jetway up to it. This further takes away that "commuter" feel of these airplanes to the pulic, and to the pilots...no more walkin across the ramp in all sorts of WX conditions like you would expect to do with a prop
Relatively high wing...basically gave up "looking down" at my wings back when i left flying the Pipers on my walk-arounds.
Anyway, just some observations...just kinda sick of hearing how all-mighty that CRJ is when in all honesty, all 'small jets' seem to be "throw away" and lack the solid construction of Boeing aircraft. I have been told the useful life of an E145 is only 17 years....SO, looks like new aircraft on the line continuously
